I personally think Old Man Logan should be Hugh's swan song.
Make it in ten years when he's clearly an older man - make it in 2020 or something. Give him that Clint Eastwood character-type that Hugh already possesses too, like an old west rogue.

Personally, I like The Lazarus Project, Enemy of the State, Shiva Scenario, the second half of Mutant Genesis, Black Sword Saga, Wounded Wolf, Blood and Claws, Not Dead Yet, Wolverine and Kitty Pryde and that one time when Wolverine was captured by Donald Pierce in the outback and tortured until Jubilee saved him. Those are the best Wolverine Storylines that don't involve a really old Wolverine.

I want to see him team up with Kitty. I love their surrogate father/daughter relationship in the comics and seeing Jackman and Page interact for an entire film would be awesome. I'd also love it if they finally brought in X-23.
